Technical Details for the GRF 503
The GRF 503 Mobile Filtration Unit sets the standard for high-performance oil care. With an impressive 50 L/min flow rate and continuous operation at 3.5 bar, it excels in filling and filtering hydraulic fluids and lubrication tanks. Connectable off-line to tanks (recommended max volume 1000 L), it supports fast flushing during start-up and acts as additional filtration for highly contaminated systems. Portable and easy to set up, it includes a wide variety of communication protocols, an electric control box with a pressure safety switch, and indicators for efficient operation. The GRF 503, with water removal option, ensures optimal performance in diverse applications.
Designed and manufactured by MP Filtri, these trolleys are a great asset to have around your hydraulic systems as they offer a great way of filtering fluids as you fill your tank.
